The NRC is announcing the availability of model applications (with model no significant hazards consideration determinations) and model safety evaluations (SEs) of the options for plant-specific adoption of Technical Specifications Task Force (TSTF) Traveler TSTF- 493, Revision 4, ``Clarify Application of Setpoint Methodology for LSSS Functions.'' TSTF-493, Revision 4, and an errata sheet are available in the Agencywide Documents Access and Management System (ADAMS) under Accession Numbers ML100060064 and ML101160026, respectively. The proposed changes revise Standard Technical Specifications (TSs) with respect to limiting safety system settings (LSSSs) assessed during periodic testing and calibration of instrumentation that may have an adverse effect on equipment operability. This model SEs will facilitate expedited approval of plant-specific adoption of TSTF-493, Revision 4.
